Hello :

All you have to do is hold the home button and the power button down at the same time for 30 to 40 seconds or until you get a Apple sign on your screen. This will reboot your iPod .

Please rate !

peter_chadwi, You forgot to mention date of manufacture from the rear cover of monitor??? If unit is out of warranty period you or qualified technician will need to investigate the units switch-mode-power-supply for proper dc voltage output. +5 v or 3.3 v and +12v Whenever strange or weird things start to occur with a cold-cathode-fluorescent-lamp back-lit lcd monitor, I would suspect the culprit to be the SMPS/inverter circuit. Hyundai lcd units have 3 year warranty. Verify that monitor does same at different "known-good" pc!! If unit still has inaccessible "menu" then start warranty service processing. Don't let Hyundai off the hook!

Send me good clear picture of the Power supply/Inverter baord and the logic board (the board with ribbon cable attached to the LCD panel and the logic board), my email is [email protected]

First of all, the screen glows white means that the inverter circuits are working and the power supply for the inverter is OK (12~18VDC is used for the inverter circuits), 5vdc for logic is more likely to be OK since you can turn it on or off. There isno way any peson can tell for sure hat it is not blown fuse or bad transistor unless he can actually make some voltage testing first. Do you have test equipment and basic knowledge of electronics? Picture will help. You can also see what usually goes bad in the monitors, http://s807.photobucket.com/home/budm/allalbums

not transistor, but it's capacitor problem. It's happen almost to all kind of LCD monitor and TV, just click here to solve your problem.

The screen has white glow and no images means that the LCD controller board (part of the LCD panel) is not getting the 5vdc power feeding it from the logic board through the ribbon cable, it is either the cable came lose or dirty contacts, or failed 5V switching transistor for the LCD controller is bad, or blown fuse on the LCD controller board.

Look at the LCD panel album.

Hi LuckyLindy

Next time this happens , just take out the main connection to the Mainboard and plug it back in.

Also remember to reset your lamp timer now that you have replaced the lamp !
